The acronym âSAP,â for Systems, Applications, and Products in Data Processing, is the name of a corporation that specializes in business products and services designed to improve operational efficiency.
In 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves. Credit: NRAO/AUI. Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from the length of a football to larger than our planet.Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna.n 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves.

Best Answer: 1.A mechanical wave is a wave that requires a medium through which to transmit energy. Sound waves, waves in a Slinky, and pressure waves are all examples of this.Sound waves need air molecules in order to exist; the Slinky waves need the Slinky, and the waves in the ocean need the water.nce this initial energy is added, the wave will travel through the medium until all the energy has been transferred. There are three types of mechanical waves. Transverse waves are waves that cause the medium to vibrate at a 90-degree angle to the direction of the wave.
